See Christina Aguilera's Sexy, Skin-Baring Halloween Costume!

In past years, the 31-year-old singer has dressed up as a sexy nurse, a corpse bride, Marie Antoinette, a skeleton and a pirate. But when Aguilera hosted a spooky party at her home in Beverly Hills Oct. 27, the Voice mentor's sexy, skin-baring costume was more ambiguous.

Aguilera is currently gearing up for the release of her seventh studio album, Lotus, in stores Nov. 9. "I can't wait for my fans to hear this album," Aguilera tells Us Weekly. "There are a few tracks that I know people are going to really connect to. . . Many of my past albums had clear cut themes and styles, but with this album, I really just put songs on the record that felt good."
